| Abstract: | This paper describes the modified factor analysis approach which is based on the concepts of nonzero-intercept and simulated pure component curve can be used to simultaneously determine complicated system. The color reaction of p-nitro-phenylfluorone and cationic surfactant (CTMAB) with germanium, molybdenum, tungsten and tin has been investigated. The optimum condition for the simultaneous determination of the four elements is discussed. Satisfactory results can be got for steel samples as well as synthetic samples by applying our present method. |
